Description

Technical Field

[0001] This disclosure relates to the technical field of energy storage power supplies, and in particular to a soft-pack battery cell support structure, a power supply module, and an energy storage power supply. Background Technology

[0002] With the transformation of the national energy structure and the increase in the proportion of renewable energy, energy storage systems, as a core component for balancing grid fluctuations and improving energy efficiency, are facing increasingly urgent technological iteration needs. Traditional energy storage power sources are limited by cell energy density, safety, and space utilization, making it difficult to meet market demands for high density, long lifespan, and lightweight design. Against this backdrop, pouch cells, with their core advantages such as high energy density, safety, and design flexibility, have demonstrated significant adaptability in the energy storage power source field, becoming a direction for technological breakthroughs. However, because pouch cell shells are flexible and lack rigid support, rigid supports are needed to house and protect the pouch cells, such as the pouch square lithium battery module structure proposed in existing technology patent CN205960064U.

[0003] However, during the charging and discharging process, pouch cells undergo a 5%-15% volume expansion, creating dynamic compression with the rigid support. This causes the pouch cells to continuously experience uneven stress, leading to stress concentration. This can easily result in the aluminum-plastic film cracking or interface delamination, ultimately causing internal short circuits and significantly reducing the lifespan and safety of the pouch cells. Furthermore, the aluminum-plastic film encapsulation process introduces dimensional tolerances of ±0.5mm in the length, width, and thickness directions of the pouch cells. This creates gaps between the inner wall of the support and the pouch cell support, making it prone to collisions when subjected to vibrations or other external factors. This further reduces the lifespan and safety of the pouch cells. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a pouch cell support structure, power supply module and energy storage power supply that can effectively improve the service life and safety of pouch cells.

[0005] The purpose of this disclosure is achieved through the following technical solution:

[0006] A soft-pack battery cell support structure includes a support body, the support body forming a battery cell mounting area, the battery cell mounting area being used to accommodate soft-pack battery cells for mounting a power supply module;

[0007] The pouch cell support structure also includes an elastic buffer pad, which is disposed in the cell mounting area. One side of the elastic buffer pad is mounted on the inner peripheral wall of the cell mounting area, and the other side of the elastic buffer pad is used to elastically support the pouch cell so that the pouch cell is confined within the cell mounting area.

[0008] In one embodiment, the thickness of the elastic cushioning pad ranges from 4.5 mm to 6.5 mm.

[0009] In one embodiment, the pouch cell support structure further includes an insulating buffer pad, which is installed in the cell mounting area and is used to be disposed between two adjacent pouch cells.

[0010] In one embodiment, the thickness of the insulating cushioning pad ranges from 1.5mm to 3.5mm.

[0011] In one embodiment, the insulating cushioning pad has a perforated area.

[0012] In one embodiment, the pouch cell support structure further includes a heat dissipation cover plate, which is detachably installed on the support body and covers the cell mounting area, and is used to abut against the pouch cell.

[0013] In one embodiment, the support body is formed with multiple cell mounting areas.

[0014] In one embodiment, the support body further forms a tab limiting groove that communicates with the cell mounting area, the tab limiting groove being used to limit the tabs of the pouch cell.

[0015] In one embodiment, a snap-fit ​​post is formed on a first side of the bracket body, and a snap-fit ​​groove adapted to the snap-fit ​​post is formed on a second side of the bracket body.

[0016] A power supply module is used to be installed and fixed in an energy storage power source, including a pouch cell and a pouch cell support structure as described in any of the above embodiments. The cell mounting area accommodates the pouch cell for mounting the power supply module, and the elastic buffer pad elastically supports the pouch cell to confine the pouch cell within the cell mounting area.

[0017] In one embodiment, the outer peripheral wall of the pouch cell is provided with a supporting flange, which is disposed opposite to the inner peripheral wall of the cell mounting area.

[0018] An energy storage power supply includes the power supply module described in the above embodiments.

[0019] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:

[0020] 1. The aforementioned soft-pack battery cell support structure also includes an elastic buffer pad. This elastic buffer pad is positioned within the battery cell mounting area. One side of the elastic buffer pad is mounted on the inner circumferential wall of the battery cell mounting area, while the other side provides elastic support to the soft-pack battery cell. This confines the soft-pack battery cell within the battery cell mounting area. When the soft-pack battery cell is installed in the battery cell mounting area, the elastic buffer pad can fill the gap between the inner circumferential wall of the battery cell mounting area and the soft-pack battery cell through its own elastic deformation. This allows the inner circumferential wall of the battery cell mounting area to fit tightly against the soft-pack battery cell, ensuring the soft-pack battery cell is securely confined within the battery cell mounting area. This effectively prevents damage or even destruction of the soft-pack battery cell due to collisions with the inner circumferential wall of the battery cell mounting area, thereby significantly improving the service life and safety of the energy storage power supply.

[0021] 2. When the pouch cell expands in volume, the elastic buffer pad can disperse and buffer the stress between the inner peripheral wall of the cell installation area and the pouch cell, effectively preventing stress concentration caused by the continuous uneven stress. This greatly reduces the possibility of internal short circuits caused by aluminum-plastic film rupture or interface delamination, further improving the service life and safety of the energy storage power supply.

[0035] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0036] like Figures 1 to 8 As shown, an embodiment of the soft-pack battery cell support structure 100 includes a support body 110, which forms a battery cell mounting area 111 for accommodating a soft-pack battery cell 200 for mounting a power supply module 10. The soft-pack battery cell support structure 100 also includes an elastic buffer pad 120 disposed within the battery cell mounting area 111. One side of the elastic buffer pad 120 is mounted on the inner peripheral wall of the battery cell mounting area 111, and the other side of the elastic buffer pad 120 is used to elastically support the soft-pack battery cell 200, thereby confining the soft-pack battery cell 200 within the battery cell mounting area 111. This allows the elastic buffer pad 120 to fill the gap between the inner peripheral wall of the battery cell mounting area 111 and the soft-pack battery cell 200 through its own elastic deformation when the soft-pack battery cell 200 is mounted in the battery cell mounting area 111, thus ensuring that the inner peripheral wall of the battery cell mounting area 111 is within the battery cell mounting area 111. The peripheral wall can be tightly attached to the pouch cell 200 by the elastic buffer pad 120, so that the pouch cell 200 can be reliably confined within the cell mounting area 111. This effectively prevents the pouch cell 200 from being damaged or even destroyed due to mutual collision with the inner peripheral wall of the cell mounting area 111, thereby greatly improving the service life and safety of the energy storage power supply. When the pouch cell 200 expands in volume, the elastic buffer pad 120 can disperse and buffer the stress between the inner wall of the cell mounting area 111 and the pouch cell 200, effectively preventing the pouch cell 200 from stress concentration due to continuous uneven stress. This greatly reduces the possibility of internal short circuit caused by aluminum-plastic film rupture or interface delamination, further improving the service life and safety of the energy storage power supply.

[0037] The aforementioned pouch cell support structure 100 further includes an elastic buffer pad 120. The elastic buffer pad 120 is disposed within the cell mounting area 111. One side of the elastic buffer pad 120 is mounted on the inner peripheral wall of the cell mounting area 111, and the other side of the elastic buffer pad 120 elastically supports the pouch cell 200, thereby confining the pouch cell 200 within the cell mounting area 111. This allows the elastic buffer pad 120 to move freely when the pouch cell 200 is mounted in the cell mounting area 111. The elastic deformation of the body fills the gap between the inner peripheral wall of the cell mounting area 111 and the soft-pack cell 200, so that the inner peripheral wall of the cell mounting area 111 can be tightly attached to the soft-pack cell 200 through the elastic buffer pad 120. This allows the soft-pack cell 200 to be reliably confined within the cell mounting area 111, effectively preventing damage or even destruction of the soft-pack cell 200 due to mutual collision between the soft-pack cell 200 and the inner peripheral wall of the cell mounting area 111. This greatly improves the service life and safety of the energy storage power supply.

[0038] When the pouch cell 200 expands in volume, the elastic buffer pad 120 can disperse and buffer the stress between the inner wall of the cell mounting area 111 and the pouch cell 200, effectively preventing stress concentration caused by the continuous uneven stress on the pouch cell 200. This greatly reduces the possibility of internal short circuits caused by aluminum-plastic film rupture or interface delamination in the pouch cell 200, further improving the service life and safety of the energy storage power supply.

[0039] like Figure 2 and Figure 6 As shown, in one embodiment, when the pouch cell 200 expands in volume, both the elastic buffer pad 120 and the insulating buffer pad 130 can disperse and buffer the stress between the inner wall of the cell mounting area 111 and the pouch cell 200, effectively preventing stress concentration caused by the continuous uneven stress on the pouch cell 200. This greatly reduces the possibility of internal short circuits caused by aluminum-plastic film rupture or interface delamination in the pouch cell 200, further improving the service life and safety of the energy storage power supply.

[0040] like Figure 2 and Figure 5 As shown, in one embodiment, the thickness of the elastic buffer pad 120 ranges from 4.5mm to 6.5mm, so that the elastic buffer pad 120 can better fill the gap between the soft-pack battery cell 200 and the inner peripheral wall of the battery cell mounting area 111. This allows the inner peripheral wall of the battery cell mounting area 111 to be tightly fitted to the soft-pack battery cell 200 through the elastic buffer pad 120, thus reliably confining the soft-pack battery cell 200 within the battery cell mounting area 111. This effectively avoids the phenomenon of mutual collision between the soft-pack battery cell 200 and the inner peripheral wall of the battery cell mounting area 111. At the same time, it also gives the first insulating buffer pad 130 a better buffering capacity, thereby greatly improving the service life and safety of the energy storage power supply.

[0041] like Figure 2 and Figure 5 As shown, in one embodiment, the elastic buffer pad 120 is a silicone elastic buffer pad 120 or a rubber elastic buffer pad 120, so that the first elastic buffer pad 120 has better elastic deformation capability.

[0042] like Figures 2 to 4As shown, in one embodiment, the pouch cell support structure 100 further includes an insulating buffer pad 130. The insulating buffer pad 130 is installed in the cell mounting area 111 and is used to be disposed between two adjacent pouch cells 200. When the pouch cell 200 expands in volume, the insulating buffer pad 130 can disperse and buffer the stress between the two adjacent pouch cells 200, avoiding stress concentration caused by the continuous uneven stress on the pouch cell 200. This further reduces the possibility of internal short circuit caused by the aluminum-plastic film cracking or interface delamination of the pouch cell 200. At the same time, it can also provide electrical insulation between the two adjacent pouch cells 200, thereby greatly improving the service life and safety of the energy storage power supply.

[0043] like Figures 2 to 4 As shown, in one embodiment, the thickness of the insulating buffer pad 130 ranges from 1.5mm to 3.5mm, so that the insulating buffer pad 130 has good buffering capacity and electrical insulation capacity, thereby greatly improving the service life and safety of the energy storage power supply.

[0044] like Figures 2 to 4 As shown, in one embodiment, the insulating buffer pad 130 is a silicone elastic buffer pad 120 or a rubber elastic buffer pad 120, so that the second elastic buffer pad 120 has better elastic deformation ability and electrical insulation ability.

[0045] like Figures 2 to 4 As shown, in one embodiment, the insulating buffer pad 130 has a hollow area 131 so that the insulating buffer pad 130 has sufficient deformation space when it undergoes elastic deformation, ensuring that the insulating buffer pad 130 has good elastic deformation capability, while also reducing the amount of material used in the insulating buffer pad 130, thereby reducing the weight and production cost of the soft-pack battery cell support structure 100.

[0046] like Figures 4 to 6 As shown, in one embodiment, a limiting flange 1111 is provided on the inner peripheral wall of the cell mounting area 111. The limiting flange 1111 is used to be positioned opposite to the pouch cell 200 so that the pouch cell 200 can be more securely confined within the cell mounting area 111, which greatly improves the installation stability of the pouch cell 200 and avoids the phenomenon of the pouch cell 200 detaching from the cell mounting area 111, thereby greatly improving the stability of the energy storage power supply.

[0047] like Figures 1 to 2As shown, in one embodiment, the pouch cell support structure 100 further includes a heat dissipation cover 140. The heat dissipation cover 140 is detachably installed on the support body 110 and covers the cell mounting area 111. The heat dissipation cover 140 is used to abut against the pouch cell 200 so that the heat dissipation cover 140 can conduct heat out of the pouch cell 200, improve the heat dissipation efficiency of the pouch cell 200, reduce the possibility of thermal runaway of the pouch cell 200, and thus greatly improve the safety and service life of the energy storage power supply.

[0048] like Figures 1 to 2 As shown, in one embodiment, the heat dissipation cover 140 is an aluminum cover or a copper cover, so that the heat dissipation cover 140 has better heat conduction capability, thereby improving the heat dissipation efficiency of the pouch cell 200 bracket.

[0049] like Figures 1 to 4 As shown, in one embodiment, a buckle 115 protrudes from the outer peripheral wall of the bracket body 110, and a buckle hole 141 is formed on the inner peripheral wall of the heat dissipation cover 140 opposite to the buckle 115. The buckle 115 is engaged with the buckle hole 141 so that the heat dissipation cover 140 can be engaged and fixed at a preset position on the bracket body 110 by the buckle 115. This not only makes the heat dissipation cover 140 securely fixed on the bracket body 110, but also reduces the difficulty of installing and disassembling the heat dissipation cover 140 and the bracket body 110.

[0050] like Figures 2 to 6 As shown, in one embodiment, the bracket body 110 has multiple cell mounting areas 111, so that the bracket body 110 can mount multiple pouch cells 200, which greatly improves the space utilization of the pouch cell bracket structure 100. Compared with the design of each pouch cell 200 being equipped with a separate bracket in the related art, the pouch cell bracket structure 100 of this disclosure can effectively reduce the material usage of the bracket body 110, thereby greatly reducing the heavy production cost of the pouch cell bracket structure 100.

[0051] like Figures 2 to 6 As shown, in one embodiment, a snap-fit ​​post 113 is formed on the first side of the bracket body 110, and a snap-fit ​​groove 114 adapted to the snap-fit ​​post 113 is formed on the second side of the bracket body 110, so that two adjacent bracket bodies 110 can be snapped together and fixed by the mutual cooperation of the snap-fit ​​post 113 and the snap-fit ​​groove 114. This allows multiple soft-pack battery cell bracket structures 100 to be modularly stacked as needed, which greatly reduces the assembly difficulty of the power supply module 10, thereby not only improving the production efficiency of the energy storage power supply, but also reducing the production cost of the energy storage power supply.

[0052] like Figures 2 to 6As shown, in one embodiment, the bracket body 110 also forms a tab limiting groove 112 that communicates with the cell mounting area 111. The tab limiting groove 112 is used to limit the tabs of the soft-pack cell 200 so that the bracket body 110 can support and fix the tabs of the soft-pack cell 200, avoiding large swings or displacements of the tabs of the soft-pack cell 200 due to external factors, greatly reducing the possibility of bending or even breaking of the tabs of the soft-pack cell 200, and thus greatly improving the service life of the energy storage power supply.

[0053] like Figures 2 to 6 As shown, in one embodiment, a first snap-fit ​​pin 116 is formed on the first side of the bracket body 110, and a first snap-fit ​​hole 117 adapted to the first snap-fit ​​pin 116 is formed on the second side of the bracket body 110, so that two adjacent bracket bodies 110 can be fixed by the mutual cooperation of the first snap-fit ​​pin 116 and the first snap-fit ​​hole 117, making the fixation between the two adjacent bracket bodies 110 more reliable, thereby greatly improving the stability of the energy storage power supply.

[0054] like Figures 2 to 6 As shown, in one embodiment, a second snap-fit ​​hole 119 is formed on the first side of the bracket body 110, and a second snap-fit ​​pin 118 is formed on the second side of the bracket body 110 to match the second snap-fit ​​hole 119, so that two adjacent bracket bodies 110 can be fixed by the mutual cooperation of the second snap-fit ​​pin 118 and the second snap-fit ​​hole 119, making the fixation between the two adjacent bracket bodies 110 more reliable, thereby further improving the stability of the energy storage power supply.

[0055] This disclosure also provides a power supply module 10 for installation and fixation within an energy storage power source, including a pouch cell 200 and a pouch cell support structure 100 as described in any of the above embodiments. The cell mounting area 111 accommodates the pouch cell 200 for mounting the power supply module 10, and an elastic buffer pad 120 elastically supports the pouch cell 200 to confine the pouch cell 200 within the cell mounting area 111.

[0056] like Figures 2 to 4 As shown, in one embodiment, the outer peripheral wall of the soft-pack battery cell 200 is provided with a supporting flange 210. The supporting flange 2111 is disposed opposite to the inner peripheral wall of the battery cell mounting area 111 to avoid direct collision between the soft-pack battery cell 200 and the inner peripheral wall of the battery cell mounting area 111 when the power supply module 10 is affected by external factors, thereby improving the service life and safety of the soft-pack battery cell 200.

[0057] like Figures 2 to 4As shown, in one embodiment, the support flange 210 is an elastic support flange, so that the elastic support flange can buffer and disperse the stress between the soft-pack battery cell 200 and the inner peripheral wall of the battery cell mounting area 111, which greatly reduces the possibility of damage or even short circuit of the soft-pack battery cell 200, and further improves the service life and safety of the soft-pack battery cell 200.

[0058] This disclosure also provides an energy storage power supply, including the power supply module 10 described in the above embodiments.

[0059] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:

[0060] 1. In the aforementioned energy storage power supply, the soft-pack battery cell support structure 100 further includes an elastic buffer pad 120. The elastic buffer pad 120 is disposed within the battery cell mounting area 111. One side of the elastic buffer pad 120 is mounted on the inner peripheral wall of the battery cell mounting area 111, and the other side of the elastic buffer pad 120 is used to elastically support the soft-pack battery cell 200, thereby confining the soft-pack battery cell 200 within the battery cell mounting area 111. This ensures that when the soft-pack battery cell 200 is installed in the battery cell mounting area 111, the elastic buffer pad 120 can utilize its own elasticity to... The deformation fills the gap between the inner peripheral wall of the cell mounting area 111 and the soft-pack cell 200, allowing the inner peripheral wall of the cell mounting area 111 to fit tightly against the soft-pack cell 200 through the elastic buffer pad 120. This ensures that the soft-pack cell 200 is securely confined within the cell mounting area 111, effectively preventing damage to the soft-pack cell 200 caused by mutual collision with the inner peripheral wall of the cell mounting area 111. This significantly improves the service life and safety of the energy storage power supply.

[0061] 2. When the pouch cell 200 expands in volume, the elastic buffer pad 120 can disperse and buffer the stress between the inner wall of the cell mounting area 111 and the pouch cell 200, effectively preventing stress concentration caused by the continuous uneven stress on the pouch cell 200. This greatly reduces the possibility of internal short circuits caused by aluminum-plastic film rupture or interface delamination in the pouch cell 200, further improving the service life and safety of the energy storage power supply.

[0062] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
